Successfully complete the game with all keyholes, 99 Dalmatians, and the Hades Cup.

Infinite magic

This method requires that you have the summons spell Bambi, which you can get in 100 Acre Woods. The abilities of Treasure Magnet and Jackpot are also very good to have. Unlimited magic is actually quite intuitive, though not necessarily obvious to all players: Summon Bambi, and have the Treasure Magnet and Jackpot abilities on. This enables the quick collection of, and increases the number of Magic Bubbles Bambi drops, respectively. You will get magic back at an incredible rate. This can be used throughout a battle, or simply to refill your magic at the end of a battle without the need for Ethers. It is best to summon Bambi and fill up your magic bar just before killing the last creature you are fighting. Also, unlimited magic also means unlimited health when coupled with the Cure spell. Of course, Bambi will not appear everywhere, such as the Coliseum, where this method would be extremely useful.

Easy money

Use the "Infinite magic" trick to help collect items and money. Find an open area where a lot of enemies appear, use your area effect spells, especially Thunder, repeatedly then run around and collect everything that falls. Remember to equip Treasure Magnet to help collect and Jackpot on as many party members that have it to increase the item drop rate. A good location to try this is Traverse Town's second and third districts after closing up the Keyhole.

Get 200 Mushrooms in the first town. You can sell them at Trevers Town to get extra life.

Fighting

Try to master using both the Left Analog-stick and Right Analog-stick. Remember to top up your partners' items. Use lock-on targeting in all Boss fights. Do not always rely on your partners to heal you. Try to use the hit and magic attack method. For example, first lock on the target. Next, use your magic until one last MP remains then join in the pounding of the Boss. Cast magic when you regain one block of MP. Continue to pound the Boss. Remember to take care of your HP during the pounding.

Easy experience

When you first start, you can fight Riku, Wakka, Tidus, and Selphie by talking to them. A good way to get experience is to fight Wakka or Riku, however if you defeat them all and get the items you need for the raft (the two logs, the cloth, and the rope) and select "Rest", when you wake up in the morning you can fight everyone except Riku. Defeat Wakka and Selphie then talk to Tidus. He will tell you about his three on one match with Riku and how bad he lost. You will then have three options, Select "3 on 1", and you will start fighting against Wakka, Tidus, and Selphie. Tidus and Selphie attack in a group. Knock out Tidus, then Selphie. Keep your distance from Wakka. When he throws the Blitzball at you and it is about to hit, slash your sword. It should be deflected, and you will get 1 or 2 experience points. You can repeat this as many times as needed, but if you hit Wakka with the ball a certain amount of times he will die. Even though it may take practice hitting the Blitzballs, it is the easiest way to get experience at the start of the game. It is possible to leave Destiny Island at level 12, almost strong enough to defeat Cloud.

Defender Shield

After you seal the Key Hole in Hollow Bastion, return and kill as many Defenders as possible. Defenders are the lion head enemies with the hardcore shields. One will eventually drop The Defender Shield, which is Goofy's second best shield.

Dream weapons

Play the White Mushrooms game, and only cast the same spell on them three times in a row. Once you use every spell this way, return to Merlin. He will give you the Dream Shield. For the Dream Rod, you need the highest level of all the spells. Once you have all the spells at the highest level, speak to Merlin. He will give you the Dream Rod.

Oblivion

After defeating Riku for the last time in Hollow Bastion, return once you regain control of the Gummi ship. Go to where you fought Riku and go up the stairs to the wall opposite the Keyhole entrance. There will be a chest there containing Oblivion, one of Sora's strongest weapons.

Save The King

Complete the Hades Cup Time Attack to get the Save The King (Goofy's best weapon).

Save The Queen

Complete the Hades Cup alone (only with Sora). As a prize, you will get Save The Queen, which is Donald's best and final magic rod.

Ultima Weapon

The Ultima Weapon is the best Key in the game. Synthesize all the items. After you complete the 25th item, the Ultima Weapon will appear. This is Sora's best weapon. It requires five Lucid Gems, five Power Gems, five Thunder Gems, three Mystery Goos, and three Gales. It is very powerful and adds 2 MP.

Wizard's Relic

After you seal the Key Hole in Hollow Bastion, return and kill as many Wizards as you can find. If you kill enough of them, one will eventually drop the Wizard's Relic, which is Donald's second best magic rod.

Hit Donald, Goofy, or another companion

To hit Donald or Goofy look around and find a barrel or box. Lift it and throw it at them and it will hit them. Note: This will take life from them. Also, throw a barrel at your companions in Monstro and it will sometimes give out bubbles, HPs, and even munny.

Defeating Behemoth

At Hollow Bastion, you will have to fight a Behemoth. Climb on his back and attack his horn. Do the same thing in the Hades Cup.

Defeating Cerberus

When fighting Cerberus in the Hades Cup, attack the heads. Donald should be able to cover you. When it spits out of its mouth, run. The stuff chases after you. However, the last one is tricky -- it will attack in front of you.

Defeating Cloud

When you first get to Traverse Town, you will probably be about level 7 to 10. When you get on the Gummi Ship, go to the Coliseum and get to fight in the Tournament. Get as far as you can. Most likely you will lose to the enemies just before Cloud. If you lose to Cloud, reset the game and try again. After you lose to the enemies just before Cloud, go on your Gummi Ship. Go the opposite of Traverse Town to the Deep Jungle. When you leave left there, you will also get the Jungleking, a new Keyblade. Return to the Coliseum and you will now definitely be strong enough to defeat Cloud. Enter the customize menu and set everything constantly on Goofy and Donald except HP and MP recovery items. Put those on only in emergencies. Then, equip Goofy with Hi and Regular Potions and two Ethers, Donalds with regular Potions, and Sora with one Hi-Potion and the rest Mega Potions. You should now be able to defeat Cloud. If you want to be stronger, complete the Alice In Wonderland section after Deep Jungle. You should be strong enough for Cloud or Cerebus.

Defeating Cloud and Leon

Use the following tactics during the battle for the 20th seed. Take out Leon first. Leon is not very difficult, considering that he and Cloud fight very much alike. When he gets near the end of his life, he powers up his sword and can reach long distances for serious damage. Cloud, on the other hand, does about three moves throughout the entire battle. After defeating Leon, heal yourself and stay out of Cloud's way. Allow Donald and Goofy to take a beating. Cloud only does his rush move about six times then does a Braver. This gives time for Donald to heal Goofy and himself to still take a little life out of Cloud. Dodge Roll frequently if Cloud decides to attack you with rushes. Whenever Cloud does a Braver, use Arcanum or just flat out beat him -- he does not attack for the period that he is taking his sword out of the ground; then, jump and glide (or dodge roll) out of his way.

Defeating Ice Titan

Seal the Keyhole at Hollow Bastion. Complete the Hades Cup and a new option will appear, for the Gold Cup. Here, you will fight an old enemy from Hercules. He is too tall to hit. Stand on the bleachers and reflect his ice attacks back at him. Being level 63 is recommended.

Defeating Kurt Zisa

Seal the Keyhole at Hollow Bastion. Then, in Agrabah, go to Aladdin's house and talk to Carpet (he is jumping around frantically). He will bring you to Kurt Zisa. Hit his hands until you break the orbs, then hit his head. When he floats in a bubble, you will need to use magic, such as Mushu. Being level 65 is recommended.

Take Aladdin and Goofy with you. Aladdin will be useful for attacking and Goofy for healing. Equip your characters (including Sora) with nothing else except Potions and Hi-Potions. Also, equip Sora with his rolling technique. Immediately when the fight begins and your small attack screen appears, go to "Magic" and summon Tinker Bell. She will heal your characters and will prevent Sora's death once. Start attacking his hands, one combo, and move away from Kurt Zisa with your rolling technique. Keep repeating this until you destroy both of his hands and he falls. Then attack his head. After he stands up again, he will allow you use magic. The only way to inflict damage is by casting spells on him. Blizaga works well. Note: When he raises his hand, stop. You will have a whirlwind around you. Look well and roll out of it. Also, when he starts to throw fire, run after him and keep casting spells on him. When he falls for the second time, attack his head. You will get him quite angry. Keep attacking him as done the first time, but with caution. He is faster and has a new move. He will start to spin around. When he spins horizontally, jump and glide until he passes under you. When he spins vertically, run and roll. He usually always hits you when he rolls horizontally -- keep your potions ready. When he falls and you hit his head again, he will stand up again. Cast spells on him as done before, but you now has yet another new move. However, it is quite easy to evade. You will see the sand moving -- keep rolling around and do not stop or the magic balls will hit you until the largest magic ball has gotten out of the sand. Roll around the outer part of the arena. He will fall again. Once again, keep casting spells on him. If these four take down attempts are not enough to defeat him, repeat the steps. Note: This monster is actually named after the person who won the Name-In-Game sweepstakes.

Defeating Leon and Yuffie

You should be about level 35 to 40 and at least have the Three Wishes Keyblade. Follow the same customization and items as with Cloud and you will be all set. Also have all of your AP abilities that enhance attacks such as Blitz and Vortex. First of all concentrate your attacks on Yuffie, deflecting her weapon when she throws it, as done with Wakka. Kill her quickly because she can heal herself. Leon is easy at first, but after you take out a certain amount of HP his sword will turn big and blue, resembling Clouds ultimate weapon from Final Fantasy 7, only not as powerful. At that point you should change your strategy from just attacking to jumping and attacking. Also make sure that you at least have Aero. It would help Donald and Goofy, but Sora is the most important.

Defeating Malificent

You must have at least the Fairy Harp sword and be at level of 39 or higher. Let your companions take care of her heartless. You should just go after her . Jump on her platform and attack. If the platform gets too high to hit her, hit that instead. She is very resistant to magic. Using Aero will also help.

Defeating Phantom

Seal the Keyhole at Hollow Bastion. Then, go to Neverland, put Peter Pan on your team, and talk to Tinker Bell. She will bring you to Big Ben, where you will meet up with Phantom. You must attack the heart below him. It changes color. When it is red, attack with Fire; when it is blue, attack with Blizzard; etc. He will cast Death on a character. Use Stop on the hands on the clock or your character will die in 12 seconds, and they cannot be brought back. Being level 70 with a lot of MP is recommended. Note: When the hearts below him are white, use normal attacks.

Defeating Riku

Riku is very hard to defeat when you first fight him, but it is not impossible. First, let Donald and Goofy really take care of him -- he will knock around before you can even attempt to swing your sword. Just glide away. After a little while he will become mad and will ignore Donald and Goofy. He will go straight after you. Being about level 41 and at least having the Fairy Harp sword is recommended. Just glide above and whack at him to defeat him.

Defeating Rare Truffles

First, defeat Captain Hook and seal the Keyhole in London. Return to the area where you were fighting Hook and wait for some Rare Mushrooms to appear. Go back two rooms so that they have a chance to appear. As soon as they are on the screen, target one of them and make sure that you are flying first. Hit it once so that you have it in mid-air. Then, keep hitting it while you are in the air. Make sure you do not let it fall or land on any part of the ship. Doing so will cause it to vanish. You can keep it in the air easily, as long as you are also in the air with it. This allows you to get easy Mystery Goos, Elixirs and Mega Exlixirs. Repeat this trick as many times as needed. Also, try to aim them away from the ship when doing this trick.

Defeating Sephiroth

After sealing the Keyhole at Hollow Bastion, a mysterious battle appears in Phil's list of options. This battle is called the Platinum Match, and you must go one on one with the toughest Boss in the game to win.

Sephiroth is very difficult. You need to complete the Hercules Cup or lock the Hollow Bastion Keyhole. He is very fast and does a lot of damage. When you hit him, it appears that you are doing no damage, but you are. You need to hit him about twenty times to get his life bar to start moving, then he will do a finishing move where he disappears. He will appear behind and probably kill you. Being at a very high level (about 85) and having the Ultima Weapon is recommended.

When you start talking life, he will do Heartless Angel, which lowers your health to 1 and MP to 0. After his life goes down a bar or two, he will run at you and do a deadly combo. Try to stay away -- gliding will not help. When he has one bar remaining, he will glow blue and make blue orbs appear around you. He will then make a group of large blue rocks appear. They will move around the battle field in a circle, then cast Meteor. If you are lucky and remain alive after this, continue attacking him. He will do it again. When he is almost dead, he will run around and not stop, becoming very difficult to hit. Hit him a few times to winthe battle. You will get about 60,000 experience points.

The Ultima Weapon or the Oblivion (found in Hallow Bastion just on the upper level behind you after you defeat Ansem/Riku) and being at level 80 to 85 is recommended. Study his moves and attack pattern. He usually five slashes then casts Halo (three huge fire pillars). Strike him after he casts Halo, or strike him when he jumps at you and attempts a slice attack. After giving him four slashes, he fades away and appears behind you, doing a surprise slice. However, this does not happen very fast and gives you about five seconds to jump away. The "invisible" life gauge he has will wear off and he will begin to lose health. Keep repeating this until the orange appears. He will fade away and start to taunt you. He will run at you but will fade again. Use the lock function on him as soon as he fades. You will lock on him, and when you have him on sight, speed glide or run at him then slice at him to interrupt Sin Harvest move. This move is similar to Heartless Angel, but it takes away your MP as well. If you are too slow, have some Hi Potions or Elixirs ready. In his second stage, you will have be quick and use the lock on continuously. Once he fades, you will have to lock on again. Dodge all his slices, especially his special. Whenever you get hit, keep casting Curaga on yourself. Repeat the same strategy until his life gauge is yellow and green. He will call out meteors. Try to dodge them. They will thump down and spin for a bit before exploding. He will throw a huge energy ball at you which takes off quite a bit of health. Cast Curaga on yourself to help. He will turn blue, be stronger, and slash repeatedly. Having MP Rage and MP Haste will help. Slice at him when you have the chance to defeat him.

Final Fantasy prelude at Atlantica

In Ariel's Grotto, examine the music box to hear a little song, which is the Final Fantasy prelude.

Shortcut in Deep Jungle

If you hate swinging on the vines, go through the jungle tunnels. When you are in the tree house fall straight where the net is located. Go to the side where there are stairs and go down. Save the game. You can surf on trees to go to the camp or just go to their tree house. You can go to the tunnels by Gummy Ship.

Surprises at 100 Acre Woods

When in Winnie the Pooh's house, examine the clock to find a hidden "Easter Egg".

While in Rabbit's Garden, check the mailbox in front of Rabbit's house to get letters.

Postcard locations

In the Item Shop, attack the fan on the ceiling. This will be much easier if you lock on first. The second Postcard will give you a Mythril Shard.

Go up the stairs to the right of the Accessory Shop, then go up the stairs on the left, up past what resembles a display case. In the far right corner, you should see a blue box. Examine the box to get a Postcard. The third Postcard will give you a Mega-Potion.

Go to the Gizmo Shop located in the Second District and walk to the door on the other side. To the right will be a ladder. Walk up it past the bridge and across the rooftops until you reach a vertical hole that goes to the third district. Walk to the corner near the right to find the hidden postcard. The fourth postcard will give you a Mega-Ether.

There is a Postcard on the roof of the Accessory Shop. If you look down the hall past the stairs to the right of the Accessory Shop, you will see several boxes. Push the largest of these boxes next to the side of the Accessory shop to reach the roof and the treasure chest next to the chimney for one Postcard. The fifth Postcard will give you a Mythril.

As soon as enter the second district from the first district, look over to your right. You will see a treasure chest sitting on a ledge. Hop onto the street light on the edge of the street corner. That will get you close enough to make the jump onto the ledge. The sixth Postcard will give you an Elixir.

The clock that is stopped at "6:54" has two Postcards.

The blue trinity in the first district, NA.
